.To all whom if zii/ay concern.'

Beit known that l, lEiniinnn J. Fnnbii', a citizen of the v,United States, residing at Muncie, in the county of lDelaware and State of indiana, have invented a new and useful Raveling Fick-Up, of which the following is a specification.

ln the operation of diiliculty has been experienced by the failure to pick up ravelings, especially when these have become wholly or partly embedded in the nap of the carpet.

lt is the object of my present invention to overcome this dilliculty. ln accomplishing this object l provide a brush and preferaloly` associate it with the nozzlel of the vacuum cleaner, which brush is mounted so that it rolls freely len the surface to be cleaned when the nozzle is moved over such surface in one direction (preferably the receding stroke), but rolls less freely or not at all when 'the nozzle is moved in the other direction (preferably the advancing stroke), thus rubbing on such surface. During each l the brush by its rubbing acts effectively to entangle on itself, in whole or in part, all threads and ravelings on on the alternate strokes, or those in the first direction, the rolling of :the brush causes the threads and ravelings thus entangled to be wound up on the brush. The rotation of the brush is preferably a mere rolling on the floor surface, instead of a reverse rotation such as ordinary carpet sweepers have. The brush is conveniently mounted so that it can be thrown into and out of action at pleasure. f

The accompanying drawings illustrate my invention.

ln these drawings Figure l is a front elevation, with some parts broken away, oiJav vacuum cleaner nozzle equipped with one form of my raveling pick-up; Fig. 2 is a section on the line 2-2 of Fig. 1 but with the brush and its shaft in elevation; Fig. 3 is a plan view of one end of this'form of raveling picklup and its mounting; Fig. 4 is a section on the line 4-4 of Fig. 3, and also shows the shaft in section at its flattened end portion; and Fig. 5 is a perspective view showing acomplete hand operated vacuum cleaner equipped with my raveling pick-u P l have illustrated my invention in connecvacuuin cleaners much y the surface passed over, whilel tion with a vacuum cleaner infwhich the nozzle isconnected at the lower end of a diist cone 11, from the upper endlof which a pipe 12 projects, this pipe 12 carrying between its ends a piston 13 around` which nts a cylinder 14 provided with a handle 15 whereby 1t may be reciprocated manually along the pipe 12 proper valves (not shown) being provided for causing this reciprocation to produce suction within the nozzle 10. However, this particular forni of vacuum cleaner is shown merely by way of illustration. Projectingfrom theforward side ci the nozzle 10 lare two lugs 20 which on .their adjacent sides are provided with notches 21 Y. for receiving the bent ends of spring arms 22 on a brush casingk 23, there being two notches 21, Vin each of the arms for holdn ing the brush casing either down against. the ilooigfas shown in full lines in Figs.i.2

and 1, or raised from the lloor as shown in dotted lines in Figs. 2 and 4. The sides ot' these notches 21 are preferably beveled, so that in coperation with the bent ends of the spring arms 22 they will act-as yielding latches for holding the brush casing in either position while still permitting suchv brush casing to be moved from such position by the application lof sufficient force thereto, the beveled sides of the notches actingto spring together the ends of the arms 22 when the brush casing is being moved from one position to the other. Thebent ends of the spring arms 22 are provided with fingers 24; which project through holes 24 in the lugs ,20, to furnish a pivotal supportA for the arms 22. These parts l have shown in connection with, all the three forms of raveling pick-ups Which I have illustrated, although hey are not in all cases essential.

In the form of raveling pick-u shown in Figs. 1, 2, 3, and 45, each end o the brush casing 23 is provided with a notch 25, which is open downward and is shallower at its forward end than at its rearward end to provide a` shoulder 26. The whole brush casing 23 is open at the bottom, andfinounted within it is a cylindrical brush 27 the shaft of which has flattened end portions 28 projecting into th'e notches 25. These flattened portions -28 in their greatest transverse dimension exceed the width of the deeper part of the notch but not'that of the shallower and;

tions ofthenotch 25, so thatsuch rotation is merely permitted;l while when 'there is a tendency to rotate such brush inthe opposite 'or counter-clockwise direction the {iattened end'portions 28 of the hrush'shaft roll intothe deeper portions of the notches 25 andjlock between the shoulder 26 and the vrear side of the notchl 25 to prevent the brush from rotating, as shown in dotted lines in. Fig. 4.

With the parts-as shown in full lines in Figs. 2 and 4, the, brush E27` engages the floor surface, and. as the nozzle l0 is pushed i'cr- Wardfover such floor surface there is a tendency to rotate the brush 27 in a counterclockwise direction, hy reason of the friction of such brush with the Iiioorsurface; but rlaecause of the locking 4ol the end portions A 28 oi' the brush shaft in the deeperl portions of the notch 25, the brush is prevented from rotating andA rubs on the'fioor surf cle, softhat it entangles on itself, ih whole` or in part, vany ravelings, threads, or lintwhich may be on the sirface passed over. However,

36W when the nozzle 10 is moved backward over -the ioor snrface, the tendency for the brush to rotate is reversed, and such brush turns freely in a clockwise direction to wind up on itself the ravelings, lint, and threads which it, has entangled, such rolling being permitted because the attened ends 28 ot the brush shaft ride out of the deeper Vbut narrower portions of the slots 25 into the wider portions of such slof.y to free such ends from the lockingl action oi the-shonlfler 42,6.

'33. The two projecting portionsl 32 of the brush i is wide enough to receive soi 1n order to hold the brush 2"? in place in the brush frame 23 when" such tranne is not 1n Contact with the floor surface, provide a, spring latch which normally substantialiy closes the free end of each notch 25, but is preferably opposite a round portion' oi the shaft instead or" a flattened portion thereof, so that it 1s not necessary to close such ,free

projecting portions 32 which entend toiifarcl-A each other across the notch 25 near its open end, the two projecting portions 32 being joined above the notch 25 by a yoke portion readily separateto permit the enfle 2S of the shari; 27 to pass when the brush' is either removed from or put in place in the brush frame. y Claim as my invention:

ln combination, a rotatabie crush having a projecting flattened shaft enti, and a trame provided with a notch, for receiving such shaft enel, saint notch having portion which shaft end and narrow enough to .prevent turning of such shaft end therein and another portion which iswific enough both to receive end and to allow it to turn theren.- l

in Witness whereof I havehereunto set my hand at Muncie, indiane, this @8th clay of May, A.' D, one thousand nine hundred and fourteen. l c
